IMPROVEMENT IN FENCE EUR CROSSING STREAMS.

"Litige tlgtmtle referat in n time @tetas rmoet mit lurking mi nt 'the smut.

Be it known that I, W'ILLIAM MQFARILIN, of the Vtownof Jackson, in Will county, and State of Illinois, haveinvented a new and improved Fence for Crossing Streams; and I doherehy declare that the following is full, clear, andvexact description thereof, reference being had to the accompanying drawings, making a part 'of this specification.

Figure 1 represents a single length of fenceas it appears standing in its natural position, land.

Figure 2represents the same as it appears when let down for the purpose of allowing the water to pass over in 4time of a freshet.

I construct the fence of iron, or other suitable material, using for the posts albar of iron, a, of sulicient strength, hinged into the jaw, b, at the lower end, which is set firmly into a foundation in the hottoin of the stream. represents a bolt, or it may Vbe a wooden pin, passing through the jaw and post, es4 shown fig. 1, in

order, to hold the fence upright. .If the pin e be of wood, the force ot' the water and floating drift' pressing4 against the fence will break the pin, and allow the fence to fall over, as' shown in tig. 2, so that the water may- 'pass over, and prevent the fence being washed away. 'lhc lengths may he separate or joined, as may be necessary. If separate, the jaws Z1 are double, so as to admit two posts.

The fence is intended more especially for streams with rock bottoins, where it is not practicable to build ordinary fences, and for streams subject to sudden rises.

What I claim as new in my invention, and desire to secure by Letters Patent, is-` The construction and arrangement of the devices described, substantially as and for the purposes set forth.
